    A - Identify the mixture:

    The mixture of powdered charcoal and powdered sugar is considered as a homogeneous mixture. This means that you cannot identify the components with naked eye as they are uniformly distributed in the mixture.

    B - Separate components:

    You ca separate the charcoal powder from the sugar powder using the following steps:

    1 - add water. Sugar will dissolve in water while charcoal won't.

    2 - filter the solution where the powdered charcoal will remain on the filter paper and the solution of powder will pass through.

    3 - boil the sugar solution (above 100 degrees celcius). The water will evaporate and the sugar will precipitate.
